The invention discloses an overall power distribution method for a hydrogen fuel cell vehicle. According to the control strategy, the quick response of the power battery is utilized, the power battery serves as main output, the gas-electric engine serves as auxiliary output, and the power of the gas-electric engine is corrected by obtaining the SOC (the charge capacity of the battery) of the power battery, the continuous charging current and the maximum power requirement. The stable operation of the gas-electric engine is guaranteed, the gas-electric engine operates in a high-efficiency area, the service life of the gas-electric engine is effectively prolonged while fuel consumption is reduced, the power battery is kept in the high-efficiency area, fluctuation is reduced, and the service life of the power battery is also effectively prolonged.
本发明公开了一种氢燃料电池汽车整体功率分配方法。本发明的控制策略是利用了动力电池的快速响应,以动力电池为主输出,燃电发动机为辅输出,通过获取动力电池SOC(电池的荷电量)、持续充电电流、最大功率需求进行修正燃电发动机功率。保证了燃电发动机的平稳运行,燃电发动机运行在高效区,燃料消耗降低的同时有效的延长了燃电发动机的寿命,动力电池保持在高效区,波动减少,动力电池的寿命也得到了有效的延长。
